Plants require nitrogen and phosphorus but cannot efficiently absorb these nutrients from the soil. instead, they obtain the nutrients through fungi that live in their roots. in return, the fungi have access to carbohydrates manufactured by the plants. without the fungi, plants would not be healthy and abundant, and the food supply of all of the organisms in the ecosystem would be in danger. this is an example of how relationships maintain balance within an ecosystem.

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
